For the following reaction, the mass of water produced from 445g of C₅₇H₁₁₀O₆ is : 

  $2 {\mathrm{C}}_{57}{\mathrm{H}}_{110}{\mathrm{O}}_6 +163 {\mathrm{O}}_2 \to 114 {\mathrm{CO}}_2+110 {\mathrm{H}}_2\mathrm{O}$

                                         

2C₅₇H₁₁₀O_6(s)+163O_2(g)  $\to$114CO_2(g)+110H₂O_(l)
2 x 890g                                                (110 x 18g)
445g                                                     'X' g
 

X = 495g
